CONN ECTIN G T FOB, DRAINAGE FITTINGS Application filed November 27, 1928. Serial No. 322,152.

This invention relates to connecting Ts for drainage fittings, and has for one of its objects to provide a unit connecting member or T adapted for arrangement in the space between the ceiling of one room and the floor of the next room in a building which will greatly facilitate the installation of the fitting, and more particularly the revent pipesections thereof. t

More particularly, it is the object of my invention to eliminate the necessity of providing what is commonly known as a j umpover in the vent pipe section in order to enable the same to be positioned in the plane of the main waste pipe .and at right angles to a lateral extension of the connecting T with which a secondary waste pipe from a basin or other fitting is adaptedtobe connected. It is also an object of my invention to provide a one-piece unitary T or connection for the main waste pipe and vent pipe sections which is provided with reinforced internally threaded hub portions with which they waste pipe sections may be easily connected in, accurate alignment with eachother and with assurance against leakage. i 7 It is a further general object of my invention to provide a unit. or T connection for drainage, systems as above characterized, which may be readily produced atrnominal manufacturing cost, and which will materially decrease the expense incident to the installation of such drainage systems especially in connection with large building operations. With the above 'andother objects in view the invention consists in theimproved connecting unit or T for drainage systems, and in the form, construction and relative arrangement of its several parts as will be 40 hereinafter more fully described, illustrated in the accompanying drawings, and subsequently incorporated in the subjoined claims. f In the drawings, wherein I have illustrated several simple and practical embodiments of the invention, and in which similar reference characters designate corresponding parts throughout the several views,-

Fig. 2 is an enlarged detail'elevation there of partly in section;

Fig. 3 is a sectional view taken on the line 33ofFig.2; g

.Fig. 4 is an elevation looking at right angles to Fig. 2, and

Fig. 5 is a detail elevation partly in section showing a modified form of the invention. Referring in detail to the drawing, 5'designates the several ,main waste pipe sections as which extend vertically and are substantially equivalent in length to the distance between the floor and ceiling ofthe building room, while 6 designates the usual main vent pipe sections. These waste and vent pipe sections in the present invention, areconnected in vertical alignment with each other by a common j one piece T casting or connecting member generally indicated at 7. 1

The member 7has a main body portion, one side wall of which is provided with one or more connecting hubs or nipples such as that shown'at 8 whereby drain pipes extending from the bath tub, basin or other fittings may beconnected with said member. The member 7 is also formed with alaterally extending connecting nipple 9 with which a drain pipe positioned horizontally between the ceiling and floor of the building may be connected. 7 v

At one side of the drain pipe connection 8 and above and below the same, the connecting T 7 is formed with the hubs 10, the'wallsof which are comparatively thick in relation to the sidewalls of the T member so that these hubs 10 may be internally threaded as indi-. cated atll without weakenin'gthe wall structure. With these hubs, the threaded ends of the vertically aligned main drain pipe sections 5 are adapted to be connected, Before making these connections, the threads may be coated with a lead painter othersuitable sealing compound or solution, which will insure a water tight joint or connection between gach zof the drain pape sections and the mem- Heretofore, it has been customary to connect the vent pipe sections 6 with each other by interposing a connecting member between the sections and below the ceiling and with one-or both of the vertical vent pipes 171between thei'r upper and lower ends. "Also,

. having its upper end joined to the main. vent pipe 6 A-t the top of the building,theupper .which the ends of the pipe sections areisealed by lead packed joints. These vent pipe sections are positioned in the same plane as the main wast-e pipe sections 5, and since the pipe sections extendedthrough the space between the floor and ceiling of adjacent rooms, it was necessary to provide in'these 'vent pipe sections a bend orjumpover to accommodate the laterally extending drain pipe connection 9 of the connecting It is one purpose of my present improvement,

to avoid thenecessit-y of using such jumpovers in the vent pipe sections, and to this. I end, I therefore, cast integrally with the T I or 'connecting' meinber 7 a vertical conduit one side of the'lateral connecting nipple9.

section 12 in which a substantially semicircular bend 131s formedextending around 7 of the T member 7. The walls of this bend 13 in the conduit 12 aregintegral with one side-wall of the member 7 and with the-wall of the nipple 9 as clearly shown in Fig. 3

of thedrawings. '-At its upper and lower ends this conduit 12 is formed with the hubs 14L in 'whichlthe ends of the'vent pipe section 6 are adapted to be'positioned and sealed by the-lead packed joints 15. Whenthe 'mem-' bers 7 are arranged in position, these hubs 14 are located substantially at the floor line cess can be readily. had thereto and thejo'ints and the ceiling line respectively, so that ac 15 packed without great difficulty; Thus, it

willbe seen that by means of this single uni-f 'tary Trasti'ng 7 having means for the connection of the vent pipe sections as well as the drain pipe sections therewith, said vent pipe sections may be straight throughout their length, and .the connections easilyand quickly nadewithout delay incident to the difliculty o f fitting the jumpover portions- 0f the vent pipesections in'place relative to the T connection between the floor and ceilinglines'. In Fig.1 ofthe' drawings, I haveshown the horizontally "extending drain pipes 16 connected with the nipples 9 and .vertical Event pipes indicated at 17 connected with these'drainpipes 16; i The vent pipes 17 at their v-upperflendsare connected'as at 18 with the main vent pipe sections 6. If necessary, other drain pipes may be connected with --in Fig. 1 of the drawings, I have" shown an auxiharyvent pipe 19. connected at its lower end with. the toprof the T members 7 "and vent pipe section 6 extendslaterallyand is connected with theuppermost dr section'5 as indicated at 20. 1 I

In'Fig. 5 of the drawings, I have illustrated an alternative form ofthe invention, wherein. instead ofaproviding the member 7 with the conduit'section 12having the bend 13, I .may

provide the ofthe horizontally elongated ain pipe body portion with the member 7 with an integrally formed downwardly extending con duit section 21 which is adapted to project below the ceiling line, and with which the upper 'end of a vent pipe section may be connected. The top of this member 7 iscprovided with the usual hub portions with which thedrain and vent-pipe sections may be connected by the usual packed joints.

. --Fr om the foregoing description considered in connection withthe accompanying draw-' ings, the construction, manner of use and several advantagesof my invention-W111 be clearly and fully understood. It will be ap parent that my improved one piece T or univentspipe" sections, will materially facilitate j the proper installation of such drainage sys terns with a minimum of manual labor and thereby appreciablyreduce the expense incident to such installations, particularly incoIinection with-buildings'of great height. This new T or'connectin'g member, is very simple in structural form,- of great 'strength and,

durability and can be produced at substantially the same manufacturing cost, as fittings ofthis'kindllieretofore in'use I have illustrated and'desc'ribedf several simple and practicalembodiments'ot mypresent improvements, butit will neverthelessbe understood that the device. is susceptible to more or less modification in the form, proportion and relative arrangement of the several parts,and -I-a'ccordingly reserve 'thep'rivilege of; resorting to! all such legitima'te changes therein as may be 'fairlyembodied within the spirit and, scope o'fithe; invention as claimed.
